To all whom, it may concern:

Be it known that I, ZOTIQUE BEAUDRY, of Lynn, Essex county, Massachusetts, have invented certain Improvements in Tools for Trimming the Edges of Soles and Heels for Boots and Shoes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this s ecification.

This invention re ates to machines for trimming the edges of the soles of boots and shoes,the object of the invention being to provide a device which will combine a cutterguard and feather-edge guard in such a manner that the standard rotary cutters in use in the trade may be used in connection therewith without change, such device being adjustable or conformable to different sizes and widths of cutters.

The invention consists,in a machine of the character specified, of a rotary shaft and a cutter fast to said shaft and provided with cutting-teeth upon its periphery, in combination with three concentric sleeves mounted upon said shaft and adjustable as one piece longitudinally thereof, one of said sleeves constituting a cutter-guard and provided with a series of guardfingers which project between the teeth of said cutter and prevent said teeth from taking too deep a cut into the edge of the sole-shoe, another of said sleeves being an auxiliary sleeve, mounted upon said cutter-guard sleeve and adjustable longitudinally thereon, the third sleeve being a feather-edge-guard sleeve, which is provided with teeth projecting between the teeth of said cutter outside said guard-fingers, the feather-edge-guard sleeve and auxiliary sleeve being held apart by a spring. A stop fast to one of said last-named sleeves limits their movement relatively to each other, said feather-edge-guard sleeve and auxiliary sleeve being adjustable as one piece longitudinally of said cutter-guard sleeve.

The invention again consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings, Figure 1 is a plan view of my improved sole-edge trimmer, the same being shown mounted upon a portion of a shaft. Fig. 2 is a longitudinal section, partly in elevation, taken on line 2 2 of Fig. 1. Fig. 3 is a section, partly in elevation, taken on line '3 3 of Fig. 1 looking toward the right in said figure. Fig. 4 is a section taken on the end of the shaft by a screw 17.

line 4 4 of Fig. 2. Fig. 5 is a section taken on iine 5 5 of Fig. 1. Fig. 6 is a plan view of the three concentric sleeves, the cutter-guard sleeve being shown at the left in said figure and the feather-edge-guard sleeve, together with the auxiliary sleeve at the right in said figure, connected therewith. Fig. 7 is a plan view showing the feather-edge-guard sleeve and auxiliary sleeve separated and in the relative positions assumed by said sleeves when about to be connected together.

Like numerals refer to like parts through out the several views of the drawings.

In the drawings, 10 is the shaft of my improved edge-trimming machine. 11 is a rotary cutter of a well-known type provided with teeth 12 upon its periphery, said teeth or blades having a curved central cutting portion 13, which cuts the central portion of the edge of the sole, and beveled portions 14 and 15 for cutting the edge of the sole adjacent to the upper and the lower edge of the sole. 16 is a rand-guide or disk fastened to Said disk also serves the purpose of securing the cutter upon the end of the shaft 10, so as to hold the same firmly secured thereto. These portions of my improved edge-trimming machine are old and well known to those skilled in the art.

The novel portion of said machine consists in the three concentric sleeves 18, 19, and 20. The sleeve 18 is a cutter-guard sleeve, the sleeve 19 an auxiliary sleeve, and the sleeve 20 a feather-edge-guard sleeve. The sleeves 18, 19, and 20, as hereinafter described, can be adjusted as one piece longitudinally of'the shaft 10, upon which they are mounted, and the sleeves 19 and 20 can be adjusted as one piece longitudinally upon the sleeve 18, upon which they are mounted. The sleeve 18 is shown in detail at the left of Fig. 6 and consists of a hollow cylinder having an enlarged portion 21 at the left-hand end thereof provided with slots 22, extending longitudinally thereof, the portions between said slots constituting guard-fingers 23, which, as seen in Figs. 1 and 2, project between the teeth of the cutter 11 and prevent the cutting edges of said teeth from sinking too dee into the edge of the sole of the shoe whicfi operated upon.

The cutter-guard sleeve 18 is fastened to the shaft 10 by a-set-screw' 24. The auxiliary sleeve 19 is mounted upon the cutterguard sleeve 18 and is fastened thereto by a is being IIO setscrew 25. The feather-edge-guard sleeve 20 encircles the cylindrical portion 26 of the auxiliary sleeve 19 and is provided with a flange 27, against which one end of a spiral spring 28 bears, the opposite end of said spring bearing against a flange 29, formed upon the auxiliary sleeve 19. To limit the extent to which the spring 28 can move the feather-edge-guard sleeve 20 relatively to the auxiliary sleeve 19, a stop-screw 30 is provided having screw-threaded engagement with the cylindrical portion 26 of the auxiliary sleeve 19, the head of said screw projecting into a slot 31, provided in the featheredge-guard sleeve 20. The inner end or oint of said screw rojects into a groove 32, ormed in the peri'p ery and running longitudinally of the cutter-guard sleeve 18. The feather-edgeuard sleeve 20 is provided with fingers 33 at t e left-hand end thereof, which project between the teeth of the cutter 11 outside the guard-fingers 23.

In assembling the parts the feather-edgeguard sleeve 20 is slipped upon the cylindrical portion 26 of the auxiliary sleeve 19 and the stop-screw 3O screwed into the tapped hole 34, provided in said cylindrical portion, the head of the screw projecting into the slot 31 and the spiral spring resting, one end against the flange 27, the other against the flange 29, and thus tending to force the two sleeves 19 and 20 apart. The sleeve 18 is 'then slid into the interior of the auxiliary sleeve 19 and fastened thereto by the setscrew 25. The three sleeves are now joined together and are placed upon the shaft 10, to which they are fastened by the set-screw 24. It will be noted that the position of the feather-edge-guard fingers 33 with relation to the teeth of the cutter 11 and with relation to the fingers 23 of the cutter-guard sleeve 18 mag be varied by loosenin the set-screw 25 an moving the auxiliary s eeve and featheredge-guard sleeve together toward the right or left, Figs. 1 and-2, as may be desired, and in this ad ustment it will be noted that the location of the feather-edge-guard and auxiliary sleeves with relation to each other is not changed, and the tension upon the spring 28 remains the same. If one cutter be substituted for another, the thickness of said outters between opposite faces varying, the three sleeves may be adjusted by means of the set-screw 24 and moving all three of said sleeves toward the right or left, as may be desired. These adjustments, it will be noted, are very quickly and easily accomplished. When by constant use in grinding the diameter of the cutter becomes changed, a new cutter-guard sleeve 18, in which the portion 21 is 0 less diameter is substituted, and in this substitution the set-screw 25 is loosened in order to allow the removal of said cutterguard sleeve, the disk or rand-guide 16 being removed by removing the screw 17.

The fingers 23 are convexly curved at their outer ends upon their outer faces to adapt them to guide the edges of shoe-soles having a concave edge, as well as shoe-soles having a straight edg The advantages derived from my improved edge-trimmer are that the device is adapted to be used with the ordinary cutters well known in commerce for this purpose. The cutter-guard sleeve being all in one piece is very strong and is easily removed from or placed upon the machine, and the three sleeves combined bein adjustable as one piece longitudinally o the shaft insures quickness of adjustment and great durability. The same advantages are obvious in the construction of the feather-edge-guard sleeve, together with the auxiliary uardsleeve, said two sleeves forming as a w ole a single piece which is adjustable, as hereinbefore described, by simply loosening a sin le set-screw and in the adjusting of which t e tension upon the spring is not changed.

The general operation of the device hereinbefore described is as follows: The edge of the sole of the shoe is held against the periphery of the cutter with the rand-guide 16 inserted between the sole of the shoe and the upper. As the shoe is passed backward and forward upon the periphery of the cutter to trim the edge of the sole in a manner well known to those skilled in this art, the cutter removes portions of the edge of the sole and trims the portion of the sole adj acentto the edge, both on the top and bottom'thereof, the bottom of the sole adjacent to the ed 0 being further smoothed and finished by t e fingers 33 of the feather-edge guard 20, said feather-edge guard yielding for different thicknesses of soles and for different thicknesses at different parts of the same sole, being held thereagainst by the spring 28.

Having thus described my invention, what I claim, and desire by Letters Patent to secure, 1s
